The railway crossed a rhyne at Portishead over two separate metal bridges, one of which survives. (A rhyne is a drainage ditch pronounced ‘reen’ - see Wikipedia entry).

The first bridge (when leaving Portishead station) is now obliterated by the current Wyndham Way road bridge, but remains of the second bridge (when leaving Portishead station) are covered in undergrowth and is on the left of Wyndham Way when approaching Portishead by road just before the road bridge. The old railway bridge can’t be seen from the road. Click photos to enlarge.
